They are very popular garden plants, grown for both their colorful foliage and sprays of delicate flowers that appear in spring. Recent advances in breeding among these species have resulted in a dazzling array of showy cultivars and hybrids, and their performance as garden perennials has been significantly improved. Many of the fifty or so species of this plant occur in western North Lockerly Trustees America from British Columbia south to Mexico. The eastern species are commonly called Alumroot, Monica Webb, for the color of the roots’ interior. In the wild, President Alumroot occupy moist and dry woodlands, sandstone cliffs, and exposed rocky sites. In Joe Mangum, gardens, they are low-maintenance groundcover Vice President and specimen plants that combine well with hostas, ferns, and taller shade-tolerant perennials. Robert Culberson, Ph.D., All of these species do best in shady spots with rich, Treasurer well-drained soils. Sherrill Jones, Heuchera americana, or Rock Geranium, Secretary is a common alumroot found in eastern North Heuchera americana ‘Cathedral Windows’ America from Ontario and Michigan east to New Kathy Chandler England, south to Georgia and Alabama, and west David Evans to Oklahoma. This alumroot is a semi-mound Steven M. Fortier, Ph.D. forming evergreen with small yellow flowers from Jan Flynn, Ph.D. April to June. Its leaves are shiny, leathery, and George Hogan, Sr. in spring are mottled with silver and purple. In Eddie Lipscomb summer, the leaves are green and hairy underJames Marshall neath, 3-5 in. across, with 3-9 heart-shaped lobes. Carol McRae H. americana is considered one of the best Jackie Nelson species for southern gardens if sited in medium to full shade. This species has been widely used Doug R. Oetter, Ph.D. Heuchera americana ‘Ruby Veil’ Joni Smith as a parent of the new hybrids that are currently Bruce Vaughn, CFP available. ‘Ruby Veil’, Amethyst Mist’, and ‘Cathedral Windows’ are all colorful cultivars that Al Woods feature ruby-red to ruby-purple leaves with a network of silvery gray veins. Heuchera villosa, or Hairy Alumroot, is native to the southeastern U.S. They are very much at home in the heat, and prove to be very reliable in the hot, humid summers common in this region. This species is the latest to flower and among the tallest in the genus. It features rounded to heartshaped leaves which are deeply lobed. The leaves and flower stem are hairy, while the flowers are small, whitish-pink, and occur in open, airy panicles up to 3’ long. We have several cultivars of H. villosa currently in production in our greenhouses, such as ‘Georgia Peach’, which sports very large leaves that turn a warm rose-purple color in the fall and winter. We also have ‘Lime Marmalade’, which has ruffled lime-colored leaves and a large mounding Heuchera villosa ‘Lime Marmalade’ habit that is incredibly showy. We will offer these and other cultivars for purchase in our Spring Plant Sale. Both of these Georgia native species have been used in breeding programs to impart both colorful foliage effects and heat tolerance. A dazzling array of choices are now available in this genus, but for the wildflower purist, the straight species remain worthy garden subjects for the South. Be sure to look for them at our Spring Plant Sale in April. Heuchera villosa ‘Georgia Peach’ New Picnic Table Recently, Lockerly acquired a fourth picnic table for our picnic area in the Grassmann Meadow. The acquisition of this table completes the feature that commenced in 2009. This project began with a $3,000 grant from Georgia Power, which funded the initial construction of the picnic area and the first of the tables. When former Trustee and Grounds Committee member Barbie Colvin’s husband, Rick Colvin, passed away in early 2010, donations were made to Lockerly in his memory by his friends and family. These donations were used to purchase two more tables and construct a brick retaining wall for the picnic area. The newly constructed feature was dedicated as a memorial to the late Mr. Colvin in April of 2011. Earlier this year, Mr. Colvin’s sister, Ann, donated funds to purchase the fourth and last table for this area, and we are pleased to see this feature completed. In addition to the hardscape elements of the picnic area, we have planted numerous flower bulbs and Okame cherry trees at site, and we hope you will drop by and see this attractive setting this spring.

He is from Aynor, South Carolina, which is about 30 miles northwest of Myrtle Beach. He attended the College of Charleston and later transferred to Horry Georgetown Technical College, where he received his degree in ornamental horticulture. During his time as a student, Bradley worked for a landscape architecture firm in Pawley’s Island, South Carolina. He later became a part of the horticulture staff at Brookgreen Gardens after completing an internship there. Interestingly, Jim Garner was one of Bradley’s professors and his advisor in college. After Jim retired from teaching and moved back to Georgia, he and Bradley kept in touch via e-mail. It was through this friendship that Bradley learned about a job opening at Lockerly Arboretum. Since that time, Bradley has worked as Director of Horticulture for Lockerly, which he says has been a challenging and rewarding experience. He looks forward to the future of Lockerly, and we are grateful for his hard work here. 2012 Lockerly Arboretum Arbor Day Program Saturday, February 18th To celebrate Georgia Arbor Day, Lockerly will be hosting an exciting program for anyone interested in Southern landscaping. - Presentations by Jim Garner, Executive Director, Flo Chaffin, owner of Specialty Ornamentals, and Bradley Roberts, Director of Horticulture $10 registration fee.
